Therefore, it is recommended to supply a stable voltage to the module by using a battery or a power frequency transformer. Do not use switching power supply (such as mobile phone charger, and any other switching power supply), power bank, switching DC-DC converter. There should not have any working D-class power amplifier, microwave oven and other equipment that will generate high-frequency electromagnetic interference.
